Description
Technical field
The invention belongs to plastics modification technology field, in particular to it is a kind of can low temperature laser carving multiple color compound and its
Preparation method.
Background technique
In prior art surface of plastic product can only generally carry out laser game of shuttlecocks it is black or it is black beat white colour, and laser carving is color
Color marker is relatively difficult.In plastic surface colour laser carving technology at present mainly based on physical adhesion and toner decomposition method,
Physical adhesion be by laser by colored thin layer it is melt bonded in plastic surface to realize colour-coded, but mark it is insecure,
Uneven color；Toner decomposition method is by laser by toner additive heat resolve, and color and material color are different after decomposition
Sample, Lai Shixian colour-coded, but since temperature is higher, thermal deformation can occur for plastic cement material or decompose to black, and color is unstable,
Limit its application.
Patent CN106566068 disclose a kind of polymer, laser marking powder and phthalocyanine pigment for laser color
The composition of engraving is thermally decomposed at a certain temperature using the phthalocyanine pigment with temperature-sensing property, thus in black tree
A kind of new color is presented in rouge surface.However, this resin combination is in laser marking, can only laser engraving go out blue and green mark
Note, other colors can not mark, and color application is limited.
Patent CN1910238 disclose a kind of polymer, colour colouring pigment and atrament etc. for laser engraving
Composition, the characteristics of being decomposed in 360 DEG C~590 DEG C temperature ranges using rainbow colorant, so as to realize
Colour is marked under label white and low energy at a high energy.This composition can black surface simultaneously realize white marking and
A kind of colour-coded, but two or more colour-coded cannot be realized simultaneously.This composition is marked for laser color
When, temperature is higher when due to laser labelling, and naval stores is heated to occur a degree of buckling deformation, while labeled tree
Fat prod surface has carbon residue deposition or different degrees of jaundice, influences color definition.
In view of the above-mentioned problems, needing to find a kind of method of new better realization low temperature colour laser carving, more face are realized
The label of the label of color or a variety of colors of same substrate, the application field range of expansion of laser light colour-coded.
Summary of the invention
Technical problem to be solved by the invention is to provide it is a kind of can low temperature laser carving multiple color compound and its preparation
Method, by laser, directly on black plastic material surface, laser carving goes out colour-coded, and by control laser in plastic surface
Two lower temperature are generated, two different colour-codeds can be gone out with laser carving.
The present invention provides it is a kind of can low temperature laser carving multiple color compound, in parts by weight, including following components: poly-
100 parts of object of conjunction, 0.1~1 part of Thermal conductive additives, 1~3 part of temperature-sensitive auxiliary agent, 0.1~1 part of color developing agent, 0.1~2 part of organic toner.
The polymer be one or more of vinyl class in polymer, phenyl quasi polymer, polyester polymer, it is right
Polymer does not require.
The Thermal conductive additives are one or more of black carbon black, titanium, iron oxide black, graphite, carbon nanotube, graphene.
Thermal coefficient >=1.2W/ (mK) of the Thermal conductive additives, effect are that even heat transmitting is allowed to disperse, and prevent office
Portion is excited to overheat, and leads to the unstable variation of color or decomposition.
The temperature-sensitive auxiliary agent is one of dione pyrrolo-pyrrole compound, due to dione pyrrolo-pyrrole chemical combination
Strong conjugation is generated between the color development system and phenyl ring of object molecule, state and the accumulation state of individual molecule can present different
The color of sample, therefore the variation of different colours can be realized by regulating and controlling the state of aggregation of dione pyrrolo-pyrrole compound.
The color developing agent is one of lithium borate, carbamide, pyrophosphoric acid, and effect is that regulation is hot at a certain temperature
The aggregated structure of quick auxiliary agent.
Organic toner is anthraquinone analog compound, phthalein blueness class compound, azo compound, Kui A Ding Tong class chemical combination
One or more of object, naphthalene nucleus ketone compounds, amino ketone compound, anthracene ketone compounds, quinophthalone class compound,
Effect is display color, can be dissolved in polymer, be uniformly dispersed, and does not have particular/special requirement to the type of organic toner.
The present invention also provides it is a kind of can low temperature laser carving multiple color compound preparation method, comprising:
(1) each raw material is pre-mixed according to the ratio uniformly, then melting extrusion is granulated, and obtains plastic particles；
(2) plastic particles for obtaining step (1) carry out melting extrusion molding or injection molding is plastic cement products；
(3) plastic cement products that step (2) obtains are subjected to by the way of laser pulse laser carving, pass through laser energy attenuation
The laser carving temperature that plastic surface generates obtains the label of multiple color.
Plastic surface in the step (3) refers to smooth surface, convex dermatoglyph face, recessed dermatoglyph face, plane, inclined-plane, curved surface or not
Regular shape.
Laser carving temperature in the step (3) is 200 DEG C and 240 DEG C.
Beneficial effect
(1) preparation method simple process of the present invention, it is economic and environment-friendly；
(2) present invention needs the surface shape of laser carving not require plastic cement products；
(3) present invention can go out two kinds of color labels by laser laser carving in black plastic material；
(4) present invention realizes the label of multiple color, and decomposition is not present, does not influence on polymer machinery performance；
Organic toner is cooperated to make material that can go out multiple color in low temperature laser carving under laser pulse simultaneously, effect is special, simple process, can use
It is decorated in product appearance, there is good market application prospect.
Specific embodiment
Below with reference to specific comparative example and embodiment, the present invention is further explained.It should be understood that these embodiments are only used for
